Abstract

CD97/ADGRE5 is an adhesion G protein-coupled receptor (aGPCR) involved in tumor cell adhesion, migration, angiogenesis, and Apoptosis. CD97 has been shown previously to stimulate angiogenesis by interacting with integrins on endothelial cells via an Arginine-Glycine-Aspartic acid (RGD) motif. In this report, the role of the RGD motif in tumor cell adhesion and Apoptosis was investigated using a previously-established HT1080 cell-based system. We found that the RGD motif is critical in CD97-promoted cell adhesion, in part due to the up-regulation of αvβ5 and α2β1 integrins, and that CD97 mediates its anti-apoptotic effect in extrinsic Apoptosis via RGD-dependent cell adhesion. In contrast, CD97-modulated anti-apoptotic effect in intrinsic Apoptosis is mediated by RGD-independent, N-cadherin-induced homotypic cell aggregation. Hence, CD97 promotes tumorigenesis via RGD-dependent and -independent mechanisms.
